Don't take chances! Responsibility and moderation are key words when it comes to consuming alcohol. When do you really know when you've had one too many?

DigitalAlcoholTester.com's Digital Alcohol Detector measures your blood alcohol level anytime you need to know if you've crossed the line between safe and not. Compact, lightweight and easy to operate, it can be used over and over again without the use of a mouthpiece and associated hygiene problems. And quick too ... a digital reading shows within seconds after blowing into the mouth vent.

The new and improved BT5500 AlcAlert model has "smart" features that make it incredibly user friendly. It tells you when to blow, and when to stop. It also warns of user error and saturation points. Take it wherever you go, or leave one in your car!
